SPIRAL WOUND GASKET
Product Type: XINSEN-SD
Features:
Experience the pinnacle of reliability and performance with this spiral wound gasket, meticulously designed with both a sturdy outer and inner ring. The addition of an inner ring significantly boosts the gasket's performance, serving multiple crucial functions. It prevents potential implosion into the pipe upon installation, shields the sealing element from extreme temperatures and aggressive mediums, and seamlessly fills the void between flanges to avert erosion, thereby ensuring a robust seal and reducing failure risks. Constructed typically from the same high-quality alloy as the winding, the inner ring adheres to the DIN 2699 standard (German), mandating its presence in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for graphite fillers. Ideal for raised and flat-faced flanges, the external guide ring provides additional radial strength, acting as a reliable compression stop to prevent blowouts. Often crafted from carbon steel with protective coatings against corrosion, the outer ring can also be tailored from specialty alloys for high-temperature and severe medium applications.
